摘    要:采用纳米银胶作为成膜亚相, 原位获得了十八胺单分子膜、十八胺/卵磷脂复合膜的表面增强拉曼信号.研究表明,增强主要来源于亚相中的银粒子与成膜分子之间较强的作用.通过在磷脂膜内添加十八胺分子辅助增强而获取了卵磷脂的分子振动信息.

关 键 词:表面增强拉曼光谱  单分子膜  分子组装  LB技术  银胶

Abstract:Surface enhanced Raman spectroscopy(SERS) has been used to study the octadecylamine(ODA) Langmuir monolayers and egg phosphatidylcholine(PC)/ODA mixed monolayers on colloidal silver subphase. The SERS enhancement results from the strong interaction between headgroups of the ODA molecules and silver nanoparticles in subphase. The results of Raman test for PC/ODA mixed monolayers show that the vibrational information of phospholipid molecules can be acquired in situ with surfactant aided SERS effect. Work based on such systems could expand the application of SERS technique in the study of Langmuir monolayers at the air water interface.
Keywords:Surface enhanced Raman scattering(SERS)  Langmuir Monolayer  Molecular assembly  Langmuir  Blodgett technique  Silver colloids
